I missed the last pill in my last pack of pills (15th October) then had my period. I then missed the first 4 pills in my new pack (23rd, 24th, 25th and 26th October), extending my pill free week to 12 days instead of 7. I had unprotected sex on the 26th of October. I took my pill the 27th and 28th, then missed 1 more on the 29th. What are the chances that I ovulated and could I get pregnant from doing this?
